The Institute for Infocomm Research (IIR) team submitted two systems, namely the primary iir_primary_llr and the contrastive iir_contrast1_llr, to the 2011 NIST Language Recognition Evaluation (LRE). Both systems are based on the fusion of multiple classifiers. These classifiers are broadly divided into two groups: acoustic and phonotactic. Included in the submission are the result files: iir1/...

Approaches to Human-Agent Modeling can broadly be categorized as the use of agents to emulate (1) the outcome and (2) the process of human behavior. The first category can be further sub-divided into emulating the outcomes produced by individual humans and by groups of humans. This position paper proposes this categorization as the core of a unified theory of human-modeling.

Explosion dynamics is a broad field of applied research based on applying the principles of thermodynamics, chemical reaction kinetics, fluid and solid mechanics to studying accidental and deliberate explosions. Research in this field and related areas such as propulsion has been carried out at Caltech since 1993 in Joe Shepherd’s Explosion Dynamics Laboratory. Our research activities can be br...

Supervised learning is a broad field that encompasses a number of methods, which can generally be classificed into two categories: parametric and nonparametric. In the parametric methods, it is assumed that the forms of the underlying density functions are known. The problem of estimating unknown functions can be reduced to estimating some values of parameters. In contrast, in the nonparametric...

This paper provides an introductory tutorial for the Interspeech07 special session on “Structure-Based and Template-Based Automatic Speech Recognition”. The purpose of the special session is to bring together researchers who have special interest in novel techniques that are aimed at overcoming weaknesses of HMMs for acoustic modeling in speech recognition. Numerous such approaches have been ta...

This review summarizes recent attempts to reconstruct the expansion history of the Universe and to probe the nature of dark energy. Reconstruction methods can be broadly classified into parametric and non-parametric approaches. It is encouraging that, even with the limited observational data currently available, different approaches give consistent results for the reconstruction of the Hubble p...

We give a complete characterization of a circle immersion that can be divided into two arc embeddings in terms of its chord diagram.
